OSBmuaj zog tshaj plywood nyob rau hauv shear.Shear qhov tseem ceeb, los ntawm nws cov tuab, yog li 2 npaug ntau dua li plywood.Qhov no yog ib qho ntawm cov laj thawj osb yog siv rau webs ntawm ntoo I-joists.Txawm li cas los xij, tus ntsia thawv tuav muaj peev xwm tswj tau qhov kev ua tau zoo hauv kev siv phab ntsa shear.

Txawm hais tias koj tab tom tsim kho, kho dua tshiab, lossis tsuas yog ua qee qhov kev kho, ntau zaus koj xav tau hom sheathing lossis underlayment rau qhov project.Muaj ntau txoj kev xaiv muaj rau lub hom phiaj no, tab sis ob qho khoom siv feem ntau yog oriented strand board (OSB) thiabplywood.Ob lub rooj tsavxwm yog ua los ntawm cov ntoo nrog cov nplaum thiab cov resins, tuaj ntau qhov ntau thiab tsawg, thiab tuaj yeem siv rau ntau lub hom phiaj.Tab sis txhua tus tsis yog tsim nyog rau txhua qhov project.Peb piav qhia qhov sib txawv ntawm lawv hauv qab no kom koj tuaj yeem txiav txim siab paub ntau ntxiv txog qhov twg yuav ua haujlwm rau koj qhov project.

Lawv Ua Li Cas

OSB thiab plywood yog tsim los ntawm cov ntoo me me thiab tuaj nyob rau hauv cov ntawv loj lossis cov vaj huam sib luag.Qhov ntawd, txawm li cas los xij, yog qhov uas qhov zoo sib xws xaus.Plywood yog ua los ntawm ntau txheej ntawm cov ntoo nyias nyias, hu ua plys, nias ua ke nrog cov kua nplaum.Nws tuaj yeem muab veneer sab saum toj ntawm hardwood, thaum cov txheej sab hauv feem ntau yog ua los ntawm softwood.

OSB yog ua los ntawm ntau daim me me ntawm hardwood thiab softwood sib xyaw ua ke hauv cov strands.Vim tias cov ntawv me me, cov nplooj ntawv ntawm OSB tuaj yeem loj dua li cov ntawv plywood.Thaum plywood feem ntau yog 6 feet ntawm ib daim ntawv, OSB yuav loj dua, mus txog 12 feet ntawm ib daim ntawv.

Qhov tshwm sim

Plywoodtuaj yeem muaj ntau yam sib txawv thiab tshwm sim.Cov txheej sab saum toj feem ntau yog cov ntoo tawv thiab tej zaum yuav yog cov ntoo xws li birch, beech, lossis maple.Qhov no txhais tau hais tias daim ntawv ntawm plywood yuav siv sij hawm qhov tsos ntawm cov ntoo saum toj kawg nkaus.Plywood ua li no yog tsim rau lub tsev txee, txee, thiab lwm yam khoom uas pom ntoo.

Plywood kuj tseem tuaj yeem ua los ntawm cov ntoo tsis zoo rau nws cov txheej saum toj kawg nkaus.Nyob rau hauv cov ntaub ntawv no, nws yuav muaj pob los yog ib tug ntxhib nto.Cov plywood no feem ntau yog siv hauv qab cov khoom tiav, xws li pobzeb lossis sab.

OSB feem ntau tsis muaj lub sab saum tojveneer .Nws yog ua los ntawm ntau cov strands los yog me me ntawm cov ntoo nias ua ke, uas muab nws ib tug rougher kev ntxhib los mos.OSB tsis yog siv rau qhov chaw tiav vim tias nws tsis tuaj yeem tuav cov xim lossis xim raws li cov ntoo plywood tuaj yeem ua tau.Yog li ntawd, nws yog feem ntau ntsia hauv qab cov khoom tiav, xws li siding.

Kev teeb tsa

Nyob rau hauv cov nqe lus ntawm structural installation rau vov tsev los yog siding, OSB thiab plywood yog heev zoo sib xws nyob rau hauv installation.Qhov sib txawv tsuas yog tias OSB hloov pauv me ntsis dua li cov plywood, uas muaj qhov zoo thiab qhov tsis zoo nyob ntawm qhov chaw thiab qhov deb ntawm cov joists uas tau them.

Nyob rau hauv ob qho tib si, cov khoom yog me me, teem rau hauv qhov chaw tiv thaiv joists, thiab nailed down securely.

Durability

OSB thiab plywood sib txawv nyob rau hauv cov nqe lus ntawm durability.OSB absorbs dej qeeb duatshaj plywood, uas tuaj yeem muaj txiaj ntsig zoo hauv thaj chaw uas tsis muaj dej noo.Txawm li cas los xij, thaum nws tau nqus dej, nws dries qeeb dua.Nws kuj warps lossis swells tom qab nqus dej thiab yuav tsis rov qab mus rau nws qhov qub.

Plywood absorbs dejsai dua, tab sis nws kuj dries sai dua.Thaum nws qhuav, nws yuav rov qab mus rau nws cov duab zoo li qub.Plywood cov npoo kuj tiv thaiv kev puas tsuaj zoo dua li OSB, uas tuaj yeem tawg thiab tawg thaum muaj kev cuam tshuam thiab dhau sijhawm.

OSB hnyav dua li plywood thiab, thaum muaj dej tsis zoo thiab khaws cia, feem ntau yuav dag.OSB kuj zoo ib yam li plywood.Plywood muaj nyob rau hauv ntau plys thiab ntau theem ntawm zoo.OSB feem ntau zoo sib xws thoob plaws lub rooj tsavxwm, lub ntsiab lus koj pom yog qhov koj tau txais.

Plywood thiab OSB feem ntau suav hais tias muaj tib lub zog thauj khoom.Txawm li cas los xij, raws li plywood tau nyob ib puag ncig ntev, nws tau pom tias nws tuaj yeem kav 50 lossis ntau xyoo hauv kev teeb tsa.OSB tsis muaj cov ntaub ntawv zoo ib yam vim nws tsuas yog ua lag luam rau li 30 xyoo.Cov ntaub ntawv pov thawj ntawm cov plywood feem ntau ua rau qee tus neeg ntseeg tias nws yog cov khoom siv ruaj khov thiab kav ntev, tab sis qhov no tsis yog qhov tseeb.Cov hom tshiab ntawm OSB, uas tau raug kho kom tsis muaj dej, zoo li yuav kav ntev npaum li cov plywood hauv cov xwm txheej zoo sib xws.

Thaum siv hauv qab flooring li substrate, plywood feem ntau suav hais tias yog cov khoom siv zoo dua.OSB flexes ntau dua plywood.Thaum siv hauv qab pobzeb, nws tuaj yeem squeak thaum nce toj ntawm qhov zoo tshaj plaws, thiab qhov phem tshaj plaws, nws tuaj yeem ua raugrout los yog pobzeb nws tus kheej kom tawg.Vim li ntawd, plywood feem ntau yog qhov pom zoo substrate yog tias xav tau ntoo substrate.

Kev txhawj xeeb ib puag ncig

Ntawm ob cov khoom, OSB suav hais tias yog qhov kev xaiv ntsuab.Vim tias OSB yog ua los ntawm ntau cov ntoo me me, nws tuaj yeem tsim tau siv cov ntoo me me, uas loj hlob sai dua thiab tuaj yeem ua liaj ua teb.

Plywood, txawm li cas los xij, yuav tsum tau siv cov ntoo loj-ntev, uas tom qab ntawd txiav tawm los tsim cov txheej uas xav tau.Cov ntoo loj dua li qhov no siv sijhawm ntev dua kom loj hlob thiab yuav tsum tau sau los ntawm cov hav zoov qub, uas ua rauplywoodibtsawg-ntsuab xaiv.

OSB tseem raug tsim los siv formaldehyde, txawm li cas los xij, thaum plywood yuav tsum tau tsim yam tsis muaj cov tshuaj no raws li cov cai tshiab ib puag ncig los ntawm lub xyoo.Hardwood plywood twb muaj cov kua nplaum nplaum thiab lwm yam ntaub ntawv uas tsis tso urea-formaldehyde rau saum huab cua.Thaum nws muaj peev xwm ua tau OSB yuav ua raws li kev cai, nws yuav sai sai nrhiav plywood yam tsis muaj formaldehyde nyob txhua qhov chaw, thaum nrhiav OSB tsis muaj cov tshuaj no yuav nyuaj dua.

Rov muag tus nqi

Cov khoom siv tsis muaj qhov cuam tshuam tiag tiag rau tus nqi muag ntawm lub tsev.Ob qho khoom siv yog suav tias yog cov qauv siv thaum siv sib piv.Thaum siv cov txheej txheem, cov ntaub ntawv raug muab zais, thiab feem ntau tsis qhia tawm thaum lub sijhawm muag, uas txhais tau hais tias lawv tsis muaj kev cuam tshuam rau cov nqi.
